Diode Series

A diode is a fundamental semiconductor device with a core composed of a PN junction, exhibiting unidirectional conductivity. Based on function, it can be categorized into rectifier diodes (e.g., the 1N4000 series, used for AC-DC conversion), fast recovery/superfast recovery diodes (e.g., the FR/SF series, suitable for high-frequency circuits), zener diodes (e.g., the 1N47 series, providing voltage regulation and protection), Schottky diodes (e.g., SS34, featuring low forward voltage drop), light-emitting diodes (LEDs, for indication and illumination), and specialized types like photodiodes and varactor diodes. Through optimized materials and structures, they fulfill differentiated circuit requirements such as rectification, voltage regulation, light emission, and optical detection, making them indispensable key components in electronic systems.
